Success can lead to complacency, and complacency is the greatest enemy of success.

Your self-confidence is directly connected to how much you feel you are making a difference in the world.

The foundation of confidence in virtually every field is preparation.

Never complain, never explain. Resist the temptation to defend yourself or make excuses.

You can accomplish virtually anything if you want it badly enough and if you are willing to work long enough and hard enough.

As a business owner or manager, you know that hiring the wrong person is the most costly mistake you can make.

Your solution for a customer has to be either amazingly valuable to someone who will pay an enormous amount of money for it or has to be valuable to an enormous number of people who pay a small amount. And also the person you're talking to-especially if you want to raise capital or raise support-has to personally say, "I want that. I like that. That sounds really great. I want that for myself."
